I just fitted these and no lights on dash work now. Any ideas why, they were working on test before i removed the bulbs now nothing.

If none of the lights are working it sounds like you have lost either the 12volt or the earth connection. Exactly which bulbs are not working? Have you just replaced the bulbs in the speedo and rev counter housing, or those in the centre console as well?

 

[Waynio]

Just had a mess more with it and this is what I am.getting.
Indicators, full beam and hand brake are fine.
The others. Speedo and tacho are near not working on ignition. Turn engine on amd rev it a bit and they get brighter. Not much though




Loose or bad connection maybe ?

 

[Waynio]

Rear ofnot looks ok. Ill.check through all the bulb holders tomorrow.

 

[johng]

does sound like a bad connection somewhere. Not likely to be the bulb holders, as they are all doing the same thing. Are the lights working okay in the centre console?

 

[Waynio]

Not working st all now j removed the console. On closer I section look like a ribbon may be damaged. May of been bad at first then on removal o made it worse.

No dash light works but as said before. No gauge lights now either.

Continuity test needed maybe.

 

[Waynio]

Thos the dash light dimmer switch is faulty. It flickers more i have been turning up and down.

Ill.remove it and investigate it.

 

[johng]

Since your indicator lights are working, it's not a ground issue. Most likely a problem with the 12volt supply that comes from the light switch. Could be the Instrument lamps fuse, or a bad connection where the plug goes into the back of the speedo unit.
Here's the layout of the printed circuit

And the circuit diagram

Defo found iys the switch/dimmer. Rehostat. More i turned it back and forth there a lot better now.
Seems full brightness now.

If i remove the switch can I get into the contacts to clean them up and contact spray them.

 

[johng]

Yes you can, here's mine after I had taken it apart.
